Circular and circular saw what is the difference
How to choose a circular saw to install on a table?
In this case, the main thing is that it should be designed for such a mode of operation. Many manual models are rated for 15/15 to 15 minutes of operation, 15 minutes to allow the engine to cool down.
In stationary mode (on the table), the saw has to work continuously, sometimes for several hours, or delay work for a long time, dramatically reducing labor productivity. Otherwise, the tool will quickly fail.
Therefore, special universal saws (hand / stationary) are produced for stationary installation. Such a saw is designed for this, which the manufacturer directly informs about in the operating instructions.
- Power: 1800 W.
- Drank depth 68 mm at a right angle, 47 mm at an angle of 45 degrees.
- Rotation speed 5,500 rpm.
- Disc diameter 190 mm, landing diameter 30 mm.
- Weight 4.7 kg.
- Price for mid-2021 is about 5,200 rubles.
Rotational speed stabilization system
This is an electronic system that, when loaded, increases the amperage supplied to the electric motor. And, conversely, it decreases when working with a low load or without it. As a result, the disc rotates at the same speed under any load.
Tip It should be remembered that the loads are not unlimited (a 1 kW motor cannot deliver a power of 2 kW).
With excessive loads, the speed will still drop or the engine will be shut off by the protective system, if any. However, the system allows for smooth operation of the saw in different modes, which makes it easier to work.
Stationary for table installation
Purely stationary circular saws do not belong to hand-held circular saws, they are sawing woodworking machines of a different class. We are talking about modifications of hand saws that can be installed on a bed with a table, saw blade up and used as a stationary machine.
Sometimes hand saws are placed on makeshift stands. It should be remembered that the hand-held cross-cut saw has a brush (collector) motor, which is not designed for long-term operation at increased loads. Namely, in this mode, the engine runs on stationary machines. Therefore, the tool will not last long with this use.
Several manufacturers offer universal hand / stationary saws. The set includes a bed with a table and a hand saw, which can be used both on the machine and for manual work.
Such options have an increased service life, designed for stationary use. In any case, the stationary option can be useful for domestic use, when you need to cut small volumes from time to time.
Circular saws of this type are structurally made in almost the same way as conventional mains saws and operate on an electric motor. The difference is that they receive power not from the electrical network, but from the batteries. The price for this type of tool is still high, but with the development of “battery” technologies, it becomes more adequate. A tool with a power source independent of the household network offers a number of obvious advantages:
- Mobility and independence from the presence of a power supply network. Can be used anywhere, even in the forest.
- Lack of wire. This makes it easier and much more convenient to work in construction, especially at a height. There is no need to lug a long extension cord, which is heavy with a long length and interferes with work, and can also get tangled.
The disadvantages of this technique are common for all battery devices:
- Less power than network models.
- Operating time limited by battery charging.
Otherwise, such saws, which are in the price range from 10 to 20, do their job well. The sawing depth declared by the manufacturer, at a cutting angle of 90 degrees. from 50 mm and more. This is enough for, for example, when building the top of a house, to cut the ends of the sheathing at a height, cut the rafters 50 mm thick, etc.
Today, there are models on sale with a modern brushless motor that has a long resource. Some manufacturers solve the problem of a limited battery life in a convenient and profitable way for professional carpenters and builders.
For example, the user is offered a whole group of cordless tools from one manufacturer. different types of saws, screwdrivers, hammer drills, wall chasers, etc. with interchangeable batteries. That is, for all equipment, only two batteries are required, which costs the owner much cheaper.
The advantages of unifying tool batteries is that one battery is suitable for both an electric screwdriver and a jigsaw or circular saw.

Without such a system, when the saw is turned off, the blade continues to rotate for some time by inertia. The electrodynamic brake, after turning off the rotation, creates a magnetic field in the motor, which slows down the rotation almost immediately. This improves safety and convenience during operation.
The circular saw has a cutting mechanism. it is a serrated disc. It serves for ripping, although with the help of additional rails, you can unfold the blade at different angles and get cross and oblique cuts. The quality of the cut is influenced by the type of blade, its diameter, the shape of the teeth and the sharpening angle. The more teeth. the lower the speed, but the quality of the cut is better. The power of circular saws ranges from one to two and a half kilowatts. Some of these tools are very difficult to handle while suspended.

A miter saw is a type of circular or circular saw. It is used for angular and inclined cuts at various angles. It differs from the above-mentioned models in that it is fixed in the bed, which in turn is connected to the work table. In this case, the disc can move up and down, maintaining the angle at which the cut will be made. You can tilt the saw using a lever.
With such a cut, the blade can be turned in different planes, while using the guides on the desktop, the blade is fed without deviating from the specified parameters. These properties make the saw popular and in demand when carrying out repair work, it can cut tiles, metal profiles in addition to wood.In addition, there are combined miter saws, where the cutting disc can turn 180 degrees in a few movements, and you can get a full-fledged circular saw. Rotating ability of the disc allows you to work with more complex workpieces.
Miter saw. it is a saw designed for repeated, fixed short cuts. It is a small mechanism with a moving electrical device that descends downward at various angles and tilts. The circular saw is a circular hand saw for sawing boards, both lengthwise and crosswise, can be fixed on the machine. The circular saw has more power than a miter saw with a blade of the same diameter, because the miter saw is designed to make a short cross-cut, and the circular saw for rip sawing The speed of the miter saw is almost always about 4500 rpm. The saw blade speed can vary from 3000 to 4500 rpm. The cutting depth of the miter saw, depending on the size of the disc, is from 40 to 130 mm, and the width, respectively, is from 70 to 363 mm. The depth of cut of the circular saw, depending on the size of the disc, is from 40 to 100 mm, and the width of the cut. respectively from 65 to 700 mm. Another useful feature of a miter saw. you can work like a regular circular one, that is, make longitudinal cuts. This saw is called a combination saw.
Power and speed
Circular saws have electric motors with a power characteristic expressed in watts (W), and for cordless models in volts (V). These numbers represent the power consumption of the motor, but they give a rough idea of how the saw will perform under load. For example, for infrequent household chores, saws with a power consumption of 1000-1300 watts are suitable. For intensive use, choose saws from 1500 W.
Speed is indicated in revolutions per minute (rpm) and manufacturers indicate this parameter at no load.

For wireless models, the battery capacity is indicated in volts and is at least 18 V or higher. Ampere-hours (Ah) is also an important indicator for rechargeable batteries: the higher the indicator, the longer you can work on a single battery charge.
Useful tips for hand saws and wood blades
When equipped with the appropriate blade, the stationary circular and hand-held circular saw can handle the following materials:
- deciduous, conifers;
- plywood, panels Particleboard, Fiberboard;
- plastic laminate;
- light steel;
- vinyl, aluminum, wood siding;
- natural stone;
- concrete blocks, paving stones;
- ceramic and quarry tiles, terracotta tiles;
- PVC and ABS pipes.
Miter Saw vs Circular Saw
- ) compared to miter saws
- Blades There are many more blade sizes available for miter saws. The miter saw blade can range from 7 “for a small miter saw to 13” for a large one. Circular saws, on the other hand, are equipped with 7¼ inch blades on average.
- Cutting type The advantage of the miter saw is that it is very accurate when cutting bevels and cross cuts. These saws are great for when you want to cut moldings, planks or skirting boards; on the other hand, the circular saw offers just as much versatility as it allows you to cut from different angles. It is also possible to tilt the disc relative to the cutting surface. Keep in mind that this will reduce the depth of cut by one and a half times. Each circular saw is equipped with a parallel stop, which helps to cut the same strips or remove “extra” width.
- Materials Circular saws can cut various types of wood and metal. The only thing you have to consider is the size of the disk. You can cut any non-ferrous metal, including copper, aluminum and brass. You can also cut ferrous metal, including thin, square or round pipes, or small corners. However, if you want to cut through any serious (over 32mm thick) metal, you need abrasive blades. Abrasive discs are thin so they can cut quickly, but not very long. Serrated blades with sintered blades are more efficient and for this reason a miter saw is better suited for cutting metals.
- Portability Most circular saws are lightweight and portable. You can carry the circular saw without any problems and even stuff it into a gym bag, while the miter saw is larger. You can load the trimmer into your car or truck, but it doesn’t offer the same mobility convenience that a circular saw can offer.
- Precision Both saws provide high cutting precision. It all depends on your specific tasks, in which one tool may be better than another. A miter saw is ready to cut easily at an angle right away, while for a circular saw you will need to install a rip fence or jig. Only then can you set the exact angles.
- Versatility Of course, circular saws are much more versatile than miter saws. This is one of the main reasons why circulars are more popular than cross-cutting.
- Ability to use When cutting at different angles with a circular saw, you must be a skilled craftsman. You need to perform additional steps to set the indents and set the desired angles when working with a circular saw. In turn, miter saws are supplied with a degree scale indicated directly on the plate. As a consequence, handling a circular saw requires more skill and experience than a miter saw.
- Safety Safety should be your top priority, especially if you are new to lumber. Because with a miter saw you will have to bring materials to the blade, the main thing is to keep your hands at a safe distance. In the case of a circular saw, you bring the blade to the workpiece, therefore more control is needed, both of the saw itself and of the lumber.
- Cleaning and maintenance Both saws are very easy to clean. The miter saw is stationary and you do not need to move it for cleaning or maintenance. However, due to its large size, a miter saw requires more time and effort than a circular saw. However, the circular saw is easy to clean thanks to its small size and portability.
- Storage The circular saw is more compact so it can be stored anywhere without creating a lot of space, while miter saws are large and therefore require more storage space.
- Which saw to buy first Again, this is a matter of experience and preference. There is no such task that a miter saw can handle and a circular saw cannot, and vice versa. Take your pick, but if your budget is tight, go for a circular saw.

Technical Parameters of Circulars
Various saw devices, even with a similar structural structure, still differ in a number of technical features. Each parameter is important because it directly affects the ability to perform certain tasks.
Features of the table circular
The stationary circular saw is a workshop equipment. It is applicable when performing a large amount of the same type of work. The presence of a table, as well as the use of various accessories together with it, allows you to achieve high accuracy when cutting.
Terms that define the function of the saw blade
Saw blades differ in the number of teeth and configuration. There are blades:
- monolithic or solid;
- with hard spraying in the working area;
- with brazed carbide plates;
- without teeth, such as a continuous rim;
- with wide and thin projections;
- with negative and positive rake angles;
- universal discs.
This variety is confusing when choosing the right drive. We’ll figure out.
A factor that is often overlooked is the availability of durable consumables for the saw you buy. For example, for each type of work, it is recommended to use a specific type of consumables: for a fast cut with rare large teeth, for a clean cut. with many small teeth.
